ryanlintott / AlignmentGuideShapeCrash.swift
Created September 14, 2024 02:18
FB15126597: AlignmentGuide crash when animating a Shape property. If an alignmentGuide affects the layout of a Shape with an animated property, changes to that property cause the app to crash. This crash occurs in Xcode 16 RC1 only when running in Swift 6 language mode.

struct CrashingView2: View {
@State private var radius: CGFloat = 10
var body: some View {
VStack {
Color.blue

Last active September 10, 2024 17:24
A fetch method that uses a parameter pack to fetch one or more PersistentModel types then runs a closure to return a Sendable result.
import SwiftData
extension ModelContext {
/// FetchDescriptor is Sendable but inside a parameter pack there are sometimes issues with this working in Swift 6.0
func fetch<each T: PersistentModel, Result: Sendable>(
_ descriptor: repeat FetchDescriptor<each T>,
with closure: @escaping @Sendable (repeat [each T]) throws -> Result
) throws -> Result {
try closure(repeat try fetch(each descriptor))
}

SwiftUI may be clipping your Text views but TextRenderer in iOS 18 might let you fix it in a far less hacky way. Hacky methods that support older OS versions can be found here: https://github.com/ryanlintott/Unicodices
