问题 I'm a complete noob at Swift (and Xcode), as a matter of fact, the only programming language I (somewhat) know is Javascript. I'm trying to make a Swift SpriteKit game, and I would like to access the number of calories burned in HealthKit. The idea is that my game will provide more points the more calories you burn using other apps like Endomondo. My app does not actually track anything, I would just like to access other data left by other apps in the Health App. Is this even possible? (I'm

But no matter what I do - for add build phase all options are disabled: I select Target -> Build Phases I have proper scheme My project runs well - no issues, I run Xcode 6 回答1: I answer on my question because took me time to find right solution. Its really strange that the same issue migrates from old versions to XCode 7+. I found solution in one of the comments of similar problem: how-to-add-a-copy

问题 A while ago I developed an iOS application using Xcode that and created a bunch of classes that work together to communicate with a RESTful API. Now I'm creating a second app, totally separate but communicates with the same API. I want to reuse these classes, what is the best way to approach this?

问题 I'm very new to Xcode (2 days) and so far I'm finding it fairly frustrating. I'm just trying to add an image to my app's ViewController via he Storyboard, but it does not appear on the simulator. Could someone assist me? 回答1: if you are trying an example project of XCode, you may find a "Images.xcassets" folder in project. Drag your image into this folder. then go to storyboard, focus on your "Image View". in the attributes list, "Image" field, you can choose the image in it's drop-down menu.

问题 We ported our codebase to use CMake for build management some weeks ago. We realize now that there is a major problem when we are trying to Archive an application that depends on one (or several) library built in the same Xcode solution. The linker fails because it cannot find the depended upon library (and the library is indeed not present where it is looking for it). minimal example Here is a minimal example producing the issue: In CMakeLists.txt ## ## The library ## project(library) add

问题 My xcode version is 6.3.1, my app is a swift project with a WatchKit target. Xcode showed this message "A signed resource has been added, modified, or deleted" when I ran it on my iPhone 6.

I tried deleting the "derived data" suggested in the question xcode 6 beta 7:A signed resource has been added modified or deleted. After I delete the "derived data", the first time I run, it stopped

问题 I'm currently taking an iOS development course and as part of my project, I'm tasked with using UIDocumentPickerViewController to import text. Every example I've found is either a) written in Objective-C or b) is for importing UIImage files. How do I set the delegate method for a text file? Here's what I've got so far: I have the iCloud capability set up. Works The delegate is specified, as follows: class MyViewController: UIViewController, UITextViewDelegate, UIDocumentPickerDelegate I have

问题 Previously with objective-c code, I could "Analyze" - CMD + Shift + B and Xcode would warn me of all kinds of wrongdoings on my part. It seems that with Swift, I can do no wrong! No warnings of any kind! But clearly there is a memory leak in my code. Is there some setting I have to enable to get Swift to analyze my code properly? (I am aware I should use the profiler and test on an actual device, which I do, but I wonder why "Analyze" doesn't do anything. 回答1: Unfortunately no. Even many
