xcode9

问题 I build the SheepShaver emulator (which, in its current version, uses SDL2 to create and display its window) for use in macOS. When I build under Xcode 9, the fonts and graphics are sharp and clear; when I build under Xcode 10 (on the same MacBook Pro running Mojave), the fonts and graphics are slightly fuzzy. I use exactly the same code when building on both Xcode versions. Is there a setting in Xcode 10 that will produce the same visual output that Xcode 9 produces? I've already got the

问题 I have a very simple framework project, MyFramework, that builds successfully. The framework defines a single, global function, myFunction. The framework also defines 2 global variables: MyFrameworkVersionNumber and MyFrameworkVersionString (These 2 variables were created for me by Xcode) I have a very simple application project, MyApplication. I am adding the framework to the application project by dragging and dropping the framework package (i.e. the MyFramework.framework in DerivedData

问题 This code works fine: let lines = ["one", "one", "two"] let lineSet = lines but while compiling this one: let lines = ["one", "one", "two"] let lineSet = Set(lines) I'm getting: Command failed due to signal: Segmentation fault: 11 I've got Xcode Version 9.0 (9A235). Is this is really a bug or am I just doing something wrong? My workaround for now: var lineSet = Set<String>() let lines = ["one", "one", "two"] lines.forEach { lineSet.insert($0) } 回答1: A better, more idiomatic way to construct

问题 I've got an array of 40 arrays with 12 double features, so the type is [[double]]. Currently I'm sending this data to Google Cloud ML API to get a related prediction. Since Apple recently introduced CoreML and coremltools, I converted my model from keras to .mlmodel to avoid thousand of google cloud api calls and do inference directly on my iPhone: coreml_model = coremltools.converters.keras.convert(new_Model, input_names=['accelerations'], output_names=['scores']) coreml_model.save(

问题 I have an existing app, that crashes on launch, when running on iPhone X Simulator. (Breakpoint stops on the main.m files). The app runs fine on iPhone 8 simulator, so it has something to with iPhone X. Also, it has something to do with the status bar, since the stack shows something with [UIStatusbar _prepareForVisualProviderIfNeeded] before the crash.

问题 Context : Xcode 9.0 (9A235) When I try to edit my storyboard label's note for localizers (inserting Barty Crouch tag #bc-ignore! ), XCode 9 crashes. Also, trying to edit the font does nothing.
