Summary:
Updates the app icon for the IGListKit iOS example app with a more modern look to reflect Instagram's style refresh in 2022.
- The shape of the bars are rounded with Apple's superellipse style and the radius is adjusted to match the curvature of the app icon itself.
- The bars now show the official Instagram 5-color gradient pattern that was released as part of the 2022 brand refresh.

Lets try using `UICollectionViewCompositionalLayout` with IGListKit! It does require some data plumbing, but maybe we can make that simpler in the future. For now, lets keep things simple and see how it feels.
This diff replicates the `MixedDataViewController` example starting with the expandable text.

Summary:
During testing, I noticed some of the UI tests would hang, and the runner would spin for hours.
I'm not sure if this was due to any code changes I made to the sample apps, or if it was just a general change in Xcode 15, but I discovered that some of the UI tests were using a for loop to 'flick' the screen until a UI element came on screen. For whatever reason, the for loop exit condition stopped working, and so now the test was stuck in an infinite loop.
This diff changes the exit condition so it properly works now, and also adds a maximum number of allowed 'flicks' just to absolutely guarantee an infinite loop isn't possible.

Summary:
The "Tail Loading" example wasn't working correctly on some iPad variants as some of the screens were too large for the number of items in the collection.
This diff:
* Enables scroll bouncing regardless of content size
* Adds more items to the list on iPad to ensure it always has some scrollable height.
* Adds `invalidateLayout()` to view size changes in order to properly handle landscape/portrait rotations.
* Hides the disclosure chevron by default (Since only the Demos view controller when running on iPhone needs it)

As part of the push for a new public release of IGListKit, I thought it'd be a good idea to go back, review the sample apps and provide some visual updates where possible. There are a lot of modern features of iOS and the other platforms that we can use to improve the look of the sample apps for free. 😁

Summary:
Fixes one final friction point for the IGListKit sample apps: SwiftLint.
At the moment, building the sample apps will hard fail if SwiftLint isn't presently installed. This is generally a good thing when adding new code to the sample apps, but for developers who might want to simply run the sample apps to try out IGListKit, this potentially adds additional unneeded friction.
Since SwiftLint also runs on each incoming PR on GitHub Actions now, even if a third party contributor submits code that they didn't lint themselves, it will still be verified by the CI.
This diff:
* Updates `lint.sh` to check for the latest version of SwiftLint.
* Makes the message that appears if SwiftLint isn't present a warning, instead of an error.
* Adds the linting script to building the `IGListSwiftKit` framework targets as well.

Summary:
This diff imports and refines the PR made by cntrump on GitHub.
The PR introduces the following:
* Sample apps now use SPM instead of CocoaPods to import IGListKit.
* Adds Mac Catalyst as an example target.
* Adds C++ flags to the CocoaPods specs.
* Fixes a script issue that was discovered when regenerating the symlinks.
The PR originally aimed to remove the need for symlinked references to the IGListKit and IGListDiffKit source files, but in testing, I couldn't get it working. It's possible SPM being too strict [on where the headers can be placed to be discovered](https://forums.swift.org/t/how-do-i-specify-the-headers-directory-for-a-objc-target-in-swift-package-managers-package-swift/58531/3).
Additionally, another issue was that the original PR changed all of the `#import` statements to the the modular `import` statements, which is fine for the sample apps, but ended up breaking compatibility for any apps that had modules disabled.
## Changes in this pull request
Improve SwiftPM support:
Build module `IGListDiffKit` and `IGListKit` as Objective-C++.
module `IGListDiffKit`:
- Source/IGListDiffKit
- module defined in `Source/IGListDiffKit/modulemap/module.modulemap`
- requires `-fmodules` and `-fcxx-modules`
module `IGListKit`:
- depend on `IGListDiffKit`, use `import IGListDiffKit;`
- Source/IGListKit
- module defined in `Source/IGListKit/modulemap/module.modulemap`
- requires `-fmodules` and `-fcxx-modules`
module `IGListSwiftKit`:
- depend on `IGListKit`, use `import IGListKit`
- Source/IGListSwiftKit
Deleted `spm/` and `scripts/generate_spm_sources_layout.sh`, it is unnecessary.
Updated `.podspec`, add `'OTHER_CFLAGS' => '-fmodules'` and `'OTHER_CPLUSPLUSFLAGS' => '-fcxx-modules'`.
Add missing swift files for `IGListSwiftKit` in `IGListKit.xcodeproj`
### How to use
Replace `#import <IGListDiffKit/IGListDiffKit.h>` with `import IGListDiffKit;`, because `IGListDiffKit.h` isn't exist in `modulemap/`, Or create a symbol link by `ln -sf ../IGListDiffKit.h` for support it ?

Summary:
A quick push to fix something I noticed while studying how IGListKit works. This simply replaces "Facebook, Inc" with "Meta Platforms, Inc" in all of the source files where the company copyright notice is posted. This should help bring our external facing projects more in line with our new corporate branding.
There's still a lot more references to "Facebook" as a company in the library (especially around linking to other Meta sponsored open source libraries), but this might need additional scrutiny and review on a case-by-case basis, so let's handle those ones separately.

I attempted to work the two frameworks into a single podspec, but it didn't really work that well. Instead, let's just split them into two podspec files - this should work fine, and more closely follows the Carthage/Xcode behavior.
This should address #1382. Note that the attached project does need to be edited, because we also need to manually specify the `IGListDiffKit` pod location. This issue will go away with the release of 4.0.

Summary:
Pull Request resolved: https://github.com/Instagram/IGListKit/pull/1377
This splits the diffing-only components from `IGListKit` out into a separate library, `IGListDiffKit`, allowing them to be used independently of the rest of `IGListKit`. We've found that the diffing components of the library are useful independently of the rest of the `UICollectionView` infrastructure, and separating the libraries allows apps to take advantage of those components without paying the full binary size cost of `IGListKit`. The diffing components are available as a subspec in Cocoapods, and as an independent framework in Carthage and direct Xcode project import (i.e. Git submodules).
This is a breaking change, necessitating a major version bump, although it should have only minor impact for projects using the umbrella header `IGListKit.h`, as that header continues to import the diffing utilities. In particular, for a project using Cocoapods and importing `IGListKit.h`, there should be no code changes required.

The error message in our Travis logs points to something related to `IGListStackedSectionController` causing the error:
```

Pretty sure the issue here is that the `xcodeproj` files were not rebuilt after deleting these files, which meant they were pointing to files that no longer existed, which caused the build to fail.

Summary:
This is a bigger PR than I'd like but there is a bunch of stuff in here that feels like we should land all at once to fix the Travis setup.
Currently, there is a few things wrong. Briefly:
1. Travis is failing to even build the library (see: [build 2298](https://travis-ci.org/Instagram/IGListKit/jobs/506564900))
2. There are legitimately failing tests
3. Travis seems to be flakey running UI tests
This PR deals with the first two.
The Xcode projects were not building because some recently added files weren't added to the xcodeproj (ie. 46a124ddfe and 4662454c4a).
Also added `Foundation.h` import for `bool` definition for `IGSystemVersion` (also a new file)
The main `Podfile.lock` was already being generated via `1.5.3` (0c0b31ad7c) but the `Gemfile` had the wrong version and none of the example project `Podfile.lock`s were re-generated with it.
Once I got the projects correctly building and tests running, I discovered there were a bunch of tests that were legitimately failing. It's unclear when these started failing and what caused it.
I thought it made sense to disable these tests for now and then create Github issues to fix them as starter tasks instead of making this diff even larger.. I can create those if that sounds good.
Somewhat related, it seems like the UI tests on Travis may be a bit flakey. They pass locally, but breaks on Travis [[example](https://travis-ci.com/bdotdub/IGListKit/jobs/195758250)] with error messages like `Failure requesting automation session for com.instagram.IGListKitExamples:85190`

> OS X uses several data types—NSInteger, NSUInteger,CGFloat, and CFIndex—to provide a consistent means of representing values in 32- and 64-bit environments. In a 32-bit environment, NSInteger and NSUInteger are defined as int and unsigned int, respectively. In 64-bit environments, NSInteger and NSUInteger are defined as long and unsigned long, respectively. To avoid the need to use different printf-style type specifiers depending on the platform, you can use the specifiers shown in Table 3. Note that in some cases you may have to cast the value.

Summary:
I had a desire for interactive reordering in a personal project, so here's a first attempt at adding support in IGListKit.
I figured I might as well get a WIP PR up for comments before I continue further as there are a few aspects to interactive reordering that don't interplay perfectly with IGListKit.
As discussed in #291, I went after two prime use cases:
1. Moving items amongst a section
2. Rearranging whole sections
I also "disabled" moving items between sections by having those moves revert, to mimic interactive reordering cancellation as closely as possible.
You can see both in the Mixed Data example. Grid items can be moved within a section, while users can be moved to reorder whole sections. But trying to move a grid item out of a grid or a user item into a grid will auto-revert. The revert animation isn't as tight as it should be. It may be more desirable to disable the animation - though you lose the visual cue.
There is a also a new example, `ReorderableViewController`, that demonstrates 2 in its pure form (likely the most desired use case), where all sections are reorderable single rows.
Happy to take feedback -- this is my first experience working on IGListKit, so I would expect there to be gaps. (Ex. I haven't used `IGListStackedSectionController`, and its tests failed as I hadn't implemented reordering delegates for it. Those are simply stubbed out for now.)
