error: module file's minimum deployment target is ios8.3 v8.3

由 我的未来我决定 提交于 2019-11-27 04:19:45
问题 All attempts to import a dynamic framework in an Xcode playground yield the following error: error: module file's minimum deployment target is ios8.3 v8.3 回答1: You might have created a target after updating Xcode, which made 8.3 the iOS Deployment Target in Build Settings for that target. I fixed this by: Setting the iOS Deployment Target to 8.0 (Which is the same as the rest of the project) Note iOS version mismatch in this screenshot (one is 10.0, other is 9.3) Note iOS versions now match

Can I import my project code into the Swift REPL?

由 拜拜、爱过 提交于 2019-11-27 03:23:00
问题 The Swift REPL is great, but it would be even better if I could import the classes from an Xcode project. I tried switching to my project directory and running $ swift > import ProjectName but I got: error: no such module 'ProjectName' Is it possible to do this? 回答1: The Swift REPL includes a number of different options. Use swift -help to see them. For your case, if you've defined ProjectName as a framework target and in the target you've declared 'Defines Module' then you can access it with

Xcode: Any way to refresh/re-run the playground?

由 元气小坏坏 提交于 2019-11-27 03:01:28
问题 The Playground in Xcode automatically updates as you type, but I can't figure out how to get the Playground to "re-compile". In many cases this wouldn't matter, but if you're writing code that generates or uses random values it can be useful to run it a few times to make sure it's working. Is there any way to get the playground to reset / refresh / re-run? Seen a few questions asking how to stop the Playground from auto-updating, but nothing for the opposite. Easiest way to do this seems to

Type does not have a member

由 不羁的心 提交于 2019-11-26 21:01:57
I'm playing around with a Swift playground working on a new class. For some reason I keep getting an error that the class "does not have a member type" with the name of a constant defined three lines earlier. Here is the code: import Foundation class DataModel { let myCalendar = NSCalendar.autoupdatingCurrentCalendar() var myData = [NSDate : Float]() let now = NSDate() let components = myCalendar.components(.CalendarUnitYear | .CalendarUnitMonth, fromDate: now) } Xcode Beta6 keeps give me an error on the second to last line, saying that "DataModel.Type does not have a member named 'myCalendar'

问题 I am working with Xcode 6, and I'm trying to recreate the code demoed during session 401 "What's new in Xcode 6". I've added an image to Images.xcassets (called Sample) and within the playground file I'm trying to access this image, as demoed. My code is as follows (like the demo): var sample = UIImage(named: "Sample") However, I can't get it to work like the demo. Am I missing something? 回答1: Open the .playground file in Finder. Create a folder called Resources next to it. Add any images you
