What does the “Embedded Content Contains Swift Code” build setting in Xcode 6 do?

阅读更多关于 What does the “Embedded Content Contains Swift Code” build setting in Xcode 6 do?

问题 It's a new setting under "Build Options". What does it do? I can't seem to find any documentation about it. My guess is this: Does it have to be set to YES in a mixed Objective-C/Swift app to tell Xcode to link against the Swift Runtime? 回答1: It does not need to be Yes for linking.

Description: Enable this setting to indicate that content embedded in a target's product

阅读更多关于 Sharing code between original iOS App and App Extension

I tried making a copy of it and putting it into the extension folder, but I of course get a invalid redeclaration of [my class] error. What's the best solution for this?

Just add required files to compile sources for your extension: Just make sure that the files you want to share gets a tick in the section Target Membership .

问题 Today extension doesn't show up in a Swift app, but it does in a Objective C app. What I did was to add a UILabel with some content on the storyboard for the swift and objective c apps. It showed up when I ran the Objective C app, but not when I executed the Swift app. Am I missing something here? 回答1: You can comment out the supplied init method. // init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) { // super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil) // //

Use Cocoapods with an App Extension

阅读更多关于 Use Cocoapods with an App Extension

I'm trying to build a photo App Extension in Xcode 6 Beta-6 that uses cocoapods libraries. The bridging header that Xcode creates for the photo extension can't see anything from cocoapods. For example: #import <GPUImage/GPUImage.h> results in the error "GPUImage/GPUImage.h" file not found . I've tried every conceivable path for the import (with brackets and quotes) and have had almost no success. The exception is that for simple pods like SVProgressHUD , the following ugly terrible hack works: #import "../Pods/SVProgressHUD/SVProgressHUD/SVProgressHUD.h" . But for GPUImage, it walks into the
