WARNING ITMS-90076: "Potential Loss of Keychain Access."

WARNING ITMS-90076: "Potential Loss of Keychain Access. The previous version of software has an application-identifier value of ['xxx'] and the new version of software being submitted has an application-identifier of ['xxx'].this will result in a loss of keychain access."

WARNING ITMS-90159: "Invalid provisioning profile. This app contains an embedded provisioning profile that is not associated with your account.Please use a provisioning profile associated with team id xxxx"

上述两个警告说的是 iTunes 转移APP 从旧账号转移了一个APP到新账号，现在要发布新的版本，然后提交的时候出现了警告。大意是provisioning profile与账号信息不匹配，需要使用新appId 申请发布证书及 provisioning profile。

ERROR ITMS-90086: Missing 64-bit support. Submission fails with error on submit app on iTunes

从2015年2月开始，发布app时必须支持64-bit。 点击项目。targets --> build setting -->Architectures -->Valid Architectures 添加arm64即可
