Xcode 14 Beta 1: the compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

• [x] I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

Attempted to compile our project using Xcode 14 beta 1 while using Charts as a Cocoapod.

What did you expect to happen?

Charts compiled

What happened instead?

/Users/bdoig/Documents/Projects/xxx/Pods/Charts/Source/Charts/Animation/ChartAnimationEasing.swift:340:39: error: the compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions internal static let EaseOutBack = { (elapsed: TimeInterval, duration: TimeInterval) -> Double in

I suspect the compiler can not infer the type of EaseOutBack and a specific type is required to be declared.

Charts Environment

Charts 3.6.0 Version 14.0 beta (14A5228q) Swift 5 iOS platform macOS 12.4

This happens under Charts 4.0.3 as well.

As noted this is with Xcode 14.0 beta 1, so Swift 5.7.

If I change ChartAnimationEasing line 340 to a func it allows it to compile. It seems like a Swift bug -- I don't see why this closure is different from the others in this file.

    internal static func EaseOutBack(elapsed: TimeInterval, duration: TimeInterval) -> Double {

same here

It also works for me if I import Charts as a Swift Package instead of a Cocoapod.

The same error occurs if I add Charts as a Cocoapod to a brand new Xcode project, using latest Cocoapods 1.11.3.

I have submitted FB10209675 with the sample project using Cocoapods to Apple.

This is a duplicate of #4835

Same error with Xcode 14 beta 2

[Brett-Best]

Seems to be fixed in Xcode 14 beta 3.
