  • Android Runtime:
  • iOS Runtime: 7.0.0
  • Plugin(s):

Having a DatePicker or Timepicker in UI makes app crash. Note this is only tested on iOS.
Below crash log is from DatePicker:

***** Fatal JavaScript exception - application has been terminated. ***** NativeScript encountered a fatal error: Uncaught Error: -[_UIDatePickerIOSCompactView _textColor]: unrecognized selector sent to instance 0x7fab415058b0 at [color:getDefault](file: node_modules/@nativescript/core/ui/date-picker/index.ios.js:61:0) at applyAllNativeSetters(file: node_modules/@nativescript/core/ui/core/properties/index.js:1091:0) at initNativeView(file: node_modules/@nativescript/core/ui/core/properties/index.js:1021:0) at onResumeNativeUpdates(file: node_modules/@nativescript/core/ui/core/view-base/index.js:695:22) at _resumeNativeUpdates(file: node_modules/@nativescript/core/ui/core/view-base/index.js:259:0) at onLoaded(file: node_modules/@nativescript/core/ui/core/view-base/index.js:214:0) at (file: node_modules/@nativescript/core/ui/core/view-base/index.js:297:0) at callFunctionWithSuper(file: node_modules/@nativescript/core/ui/core/view-base/index.js:291:0) at callLoaded(file: node_modules/@nativescript/core/ui/core/view-base/index.js:297:0) at loadView(file: node_modules/@nativescript/core/ui/core/view-base/index.js:437:0) at (file: node_modules/@nativescript/core/ui/core/view-base/index.js:216:0) at eachChildView(file: node_modules/@nativescript/core/ui/layouts/layout-base-common.js:101:0) at eachChild(file: node_modules/@nativescript/core/ui/core/view/view-common.js:700:0) at onLoaded(file: node_modules/@nativescript/core/ui/core/view-base/index.js:215:0) at (file: node_modules/@nativescript/core/ui/core/view-base/index.js:297:0) at callFunctionWithSuper(file: node_modules/@nativescript/core/ui/core/view-base/index.js:291:0) at callLoaded(file: node_modules/@nativescript/core/ui/core/view-base/index.js:297:0) at loadView(file:///app/vendor.<…>

As noted by @lochstar in NS Slack, the crash can be handled
by commenting out the following in

DatePicker.prototype[date_picker_common_1.colorProperty.getDefault] = function () {
    // return this.nativeViewProtected.valueForKey("textColor");

and setting the DatePicker to the old wheel/inline style and a @loaded event on the DatePicker component

    handleDatePickerLoaded(args) {
      // apply inline/wheel style for iOS 14+
      if (isIOS && device.osVersion >= 14.0) {
        args.object.ios.preferredDatePickerStyle = 1

Other Answers:

If you're using RadDataForm you'll notice the same thing is happening, but it looks a lot worse and is in some cases almost un-usable.

To fix this, just get the element in the editorUpdate event:

function customiseEditor(args){ args.editor.editor.preferredDatePickerStyle = 1; }

Of course you'll want to wrap this in a version check.

I hope this is helpful to someone, as this wasted me a whole day!
