Are topics getting marked as offtopic when there is an interaction of Swift with Apple's external frameworks? I don't think so. Examples:
Hi!
I created this github sample project to describe an issue with the Xcode 11 SwiftUI preview canvas pane (⌥ + ⌘ + return) in combination with the Swift package.
It seems that SwiftUI preview is working only for source files in Sources/[target] directory
(Package -> Sources -> TargetName) ,
but not in subfolders (Package -> Sources -> TargetName -> Subfolder ) .
File \FeaturePackage\Sources\FeaturePackage\SampleButton.swift
- preview is working
File \FeaturePackage\Sources\FeaturePack…
Hi! I am running into the following issue:
The goal of my code is to check a string "text" to see if it contains any variables from a list of allergens (from a different view). If one of the allergens appear in the string, then I want it to appear in the output list. So the user may list a total of 5 allergens, and if only 3 of the allergens are in the "text" string, then those 3 will appear in the output list.
However, I run into the following error: Unable to infer complex closure return typ…
The article Controlling vDSP Operations with Stride says in the “Use a Negative Stride” section:
To use a negative stride, create a pointer to the last element in the array by initializing an UnsafePointer that's advanced by the number of elements less one.
and gives the following example:
let a: [Float] = [10, 20, 30, 40, 50, 60, 70, 80]
let b: [Float] = [ 1, 2, 3, 4, 5, 6, 7, 8]
let n = vDSP_Length(a.count)
var c = [Float](repeating: .nan, count: a.count)
let strideA = vDSP_Strid…
If you look at the topics marked offtopic you will see that basically all of them are only about the frameworks, not the language, and before SwiftUI and Combine came out almost all of those questions could've been rewritten as obj-c questions because there were no interactions with the language itself.
