I got the solution, Thanks to my colleague,
我得到了解决方案，感谢我的同事，
I am capturing the image from imagePickerController and getting saved in NSData.
But the image captured it around 6-7 MB (iPad camera captures the image with this size by default)
and when saving it into NSDataand then converting it into base64 format goes out of size and then compiler throws the issue.
我正在从 imagePickerController 捕获图像并保存在NSData. 但是捕获的图像大约为 6-7 MB（iPad 相机默认捕获此大小的图像）并且在将其保存NSData并转换为 base64 格式时会超出大小，然后编译器会抛出问题。
Issue solved just by changing in line code for UIImageJPEGRepresentation
只需更改行代码即可解决问题 UIImageJPEGRepresentation
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
photoImgView.image=info[UIImagePickerControllerOriginalImage] as? UIImage
imageData = UIImageJPEGRepresentation((info[UIImagePickerControllerOriginalImage] as? UIImage)!, 0.5)
print(imageData)
picker .dismissViewControllerAnimated(true, completion: nil)
}

I got a solution for video:
我得到了视频的解决方案：
use "PHImageFileSandboxExtensionTokenKey" key
使用“ PHImageFileSandboxExtensionTokenKey”键
[PHImageManager defaultManager] requestAVAssetForVideo:asset options:avRequest resultHandler:^(AVAsset * _Nullable asset, AVAudioMix * _Nullable audioMix, NSDictionary * _Nullable info) {
NSString *localPath = info[@"PHImageFileSandboxExtensionTokenKey"];
if (localPath == nil || [localPath isEqualToString:@""]) {
isiCloud = YES;
} else {
isiCloud = NO;
}

You're calling the dissmissViewController(:_)in the beginning. Call it at the end of function and try.
你dissmissViewController(:_)在一开始就调用了。在函数结束时调用它并尝试。
