管道'DatePipe'的参数'日期格式'无效？

这似乎是一个简单的问题.我在Ionic 2应用程序中使用管道作为日期格式.这是收到的webservice响应.

Xcode 10故事板UI组件不可见并且很慢？

当我拥有Xcode 9并将代码从应用程序文件夹中删除（由于使用其他Apple ID安装的代码无法更新）并从Appstore重新安装Xcode 10时，我的代码运行正常（正确显示UI）。

现在Xcode故事板不显示任何添加的UI元素颜色或其他任何东西，我删除了Xcode 10并再次安装了Xcode 9，但问题仍然相同。

故事板的UI屏幕截图。

我尝试以这种方式删除Xcode：

/Applications/Xcode.app
/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Caches/com.apple.dt.Xcode
~/Library/Application Support/Xcode
~/Library/Developer/Xcode
~/Library/Developer/CoreSimulator

然后，我尝试安装macOs Mojave并再次从Appstore安装XCode 10。问题仍然存在。我尝试清理派生数据，xuserdata和所有内容。

它没有设定其选择的价值.我在Angular 1中做过这个.

我有一个Ionic 2应用程序,它在Chrome浏览器中工作正常,但是当它在模拟器(使用Safari进行远程调试)或实际设备上运行时,它会产生以下错误.此错误后应用程序无法完全正常工作.

Angularjs 2:选择不使用离子选择Ionic 2中的选定值进行更新？

我有下面的代码,到目前为止工作,但有一个小问题,我无法弄明白.用户选择一个选项后,它不会更新(将所选值设置为离子选择)离子选择？基本上UI没有使用选定的值进行更新？

<ion-item>
<ion-label>Classifications</ion-label>
<ion-select [(ngModel)]="selectedItem" #item (change)="onChange(selectedItem)">
<ion-option *ngFor="#item of items" [value]="item">{{item}}</ion-option>
</ion-select>
</ion-item>

onChange(selectedItem) {
   console.log('Selected item: '+selectedItem);
}

出来用户选择正确显示,我在这里缺少什么想法？

更新

<ion-item> 
  <ion-label>Gender</ion-label> 
  <ion-select [(ngModel)]="gender"> 
    <ion-option value="f" checked="true">Female</ion-option> 
    <ion-option value="m">Male</ion-option>
