我不知道这意味着什么,但我已经尝试了许多其他解决方案,例如清理,删除Derived Data文件夹,检查我的所有框架,我仍然无法解决问题.如果有人知道如何解决这个问题,我将非常感激.感谢您的时间.

这是AppDelegate.swift文件：

import UIKit
import CoreData
import Parse
import FBSDKCoreKit
import FBSDKLoginKit
import Bolts

@UIApplicationMain
class AppDelegate: UIResponder,UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent,animated: true)

    // Type casting in swift is "as Type",you'll need to unwrap optionals however.
    let tabBarController = self.window!.rootViewController as! UITabBarController
    let tabBar = tabBarController.tabBar as UITabBar

    // I prefer to use 0 based labels since the array is 0 based
    let tabBarItem0 = tabBar.items![0] as! UITabBarItem
    let tabBarItem1 = tabBar.items![1] as! UITabBarItem
    let tabBarItem2 = tabBar.items![2] as! UITabBarItem

    // The UIColor method you are using is an initializer in swift
    tabBar.tintColor = UIColor(red: 62.0/255.0,green: 191.0/255.0,blue: 180.0/255.0,alpha: 1.0)

    // UIImage also has an initializer for your situation in swift
    tabBarItem0.selectedImage = UIImage(named: "Discover TabBar Select.pdf")
    tabBarItem1.selectedImage = UIImage(named: "Me TabBar Select.pdf")
    tabBarItem2.selectedImage = UIImage(named: "Settings TabBar Select.pdf")

    //Facebook SDK Setup
    FBSDKApplicationDelegate.sharedInstance()
    Parse.setApplicationId("HxjVTJZ2rZA6qFBl0Xaji9z12HYQmTFPIXhVcfPp",clientKey:"8FJT7KHSmDPZi1AtpFS1GvTw39qevvB0JuimwWdS")

    if let launchOptions = launchOptions {
        PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
    } else {
        PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions([NSObject:AnyObject]())
    }

    // [Optional] Power your app with Local Datastore. For more info,go to
    // https://parse.com/docs/ios_guide#localdatastore/iOS
    Parse.enableLocalDatastore()

    // [Optional] Track statistics around application opens.
    PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)

    return true
}

func applicationDidBecomeActive(application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the      application was inactive. If the application was prevIoUsly in the background,optionally refresh the user interface.
    FBSDKAppEvents.activateApp()
}

我将最新的Parse和Facebook SDK框架拖到我的项目中,并通过“Build Phases”部分下的“Link Binary with Libraries”选项卡添加了所需的额外Frameworks(包括libsqlite3.dylib和libz.dylib)

我希望这些额外的信息是有用的.
