问题 I have just started learning how to make iOS apps, and am using the free personal developer account. I have made four apps so far, but do not seem to be able to install more than three apps. Even if I have three apps installed, and go to update one of the installed apps I receive the following error message in Xcode: App installation failed The maximum number of apps for free development profiles has been reached.

iOS10 适配、Xcode8配置总结

阅读更多关于 iOS10 适配、Xcode8配置总结

随着iOS10的推送更新到来，勤劳的程序员又在加班加点的搬砖了，为此收集了一些iOS10 更新的技能给大伙参考，不断更新喜欢就star 前沿一、Xcode8 插件你去哪了以为是和之前一样 Xcode 升级了，只需要更新 Xcode info.plsit 中的 DVTPlugInCompatibilityUUID,结果发现一点用都木有泪奔；苹果解决xcode ghost，把插件屏蔽了,为此也给大伙找到了相关的解决方法，但是不怎么推荐这样做，因为烦的是不能够上传 iTunes content https://github.com/inket/update_xcode_plugins 还有一种方案就是Xcode自带的注释插件！解决方法打开终端，命令运行： sudo /usr/libexec/xpccachectl 然后必须重启电脑后生效注意：Xcode8内置了开启注释的功能，位置在这里快捷键：option + common + / 01.png 二、隐私权限以及相关设置注意，info.plist 不加对应字段,访问相册,通讯录，同时添加的时候，结尾尾不要有空格警告：近期有小伙伴们用Xcode 8打包上传App，本地验证和ipa上传都正常。但是itunes connect后台的构建版本一直出不来，手机APP 端的 itunes connect收到push通知提示

My code looks like this: func getDistance (location1: CLLocation, location2: CLLocation) { let coordinates1 = location1.coordinate let placemark1 = MKPlacemark(coordinate: coordinates1) let sourceItem = MKMapItem
