Xcode 7 beta - 构建错误（xcassets）

Question

I was just install Xcode 7 beta and converted my Swift project with Swift 2 guidelines.

Build is OK but xcassets: I reached this error in logs:

CompileAssetCatalog /Users/phoenix/Library/Developer/Xcode/DerivedData/{...}/Build/Products/Debug-iphoneos/{...}.app {...}/Images.xcassets

    com.apple.CoreSimulator.SimDeviceType.iPad-2 for runtime SimRuntime :
    9.0 (13A4254u) - com.apple.CoreSimulator.SimRuntime.iOS-9-0 ((null))

UPD: Now when I try to launch iOS Simulator from "Open developer tools" menu from dock I reach this error:

Dyld Error Message:
Library not loaded:
    @rpath/SimulatorKit.framework/Versions/A/SimulatorKit
Referenced from: /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app/Conte‌​nts/MacOS/Simulator
Reason: image not found

UPD2: When trying launch simulator from terminal got warning:

$ Applications/Simulator.app/Contents/MacOS/Simulator 
dyld: warning, LC_RPATH @loader_path/../../../../Library/PrivateFrameworks in /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app/Contents/MacOS/Simulator being ignored in restricted program because of @loader_path
dyld: Library not loaded: @rpath/SimulatorKit.framework/Versions/A/SimulatorKit

  Reason: image not found

I think this is a main issue...

Answer 1

Navigate to ~/Library/Developer/CoreSimulator/Profiles/Runtimes , then remove the runtime - the runtime is old. After, reboot Xcode7, and launch the Simulator...

Further explanation from @seancook :

I experienced this, too, on El Capitan. NIBs wouldn't load, no Sims present, and unable to launch Simulators through the Xcode/Open Developer Tool/Simulator menu. After fighting it for a few hours I've finally got it working.

Here's what worked for me (YMMV): I noticed a message in Console.app along the lines of the Simulator runtime not being code signed. I went to the path it described "/Library/Developer/CoreSimulator/Profiles/Runtimes" and removed the runtimes that I had there. They were old runtimes, so I assume that some check in Xcode now applies that didn't previously. Who knows?

After doing this, I could finally launch the Simulator via the Xcode/Open Developer Tool menu. Unfortunately, the Simulator still wasn't being shown as a run target in my workspace, so I kept spelunking...

I then went into the Simulator's Hardware/Devices/Manage Devices menu and added a new iOS9 device. It didn't seem to do anything, so I quit out of Xcode and Simulator.app. I then re-started Simulator.app (via Xcode/ODT/Simulator) and lo and behold the expected iOS9 simulators were displayed. I closed and re-opened Xcode, changed the target OS for my project, and the Sims were finally displayed as run targets.

Answer 2

I was using an older xCode ( I have 8.3.1 installed by appstore and I was using 8.2.1). For me, the solution was Xcode/Preferences>Locations and setting Command Line Tools: Xcode 8.2.1 (8C1002) (it was on the newer Xcode before)

我刚刚清除了派生数据，现在工作正常。
