运行老项目

The targets “NewsTests” and “NewsUITests” contains source code developed with Swift 3.x. This version of Xcode does not support building or migrating Swift 3.x targets.
Use Xcode 10.1 to migrate the code to Swift 4.

目前版本

Swift Compiler - Language 选择一个高版本吧

pod 保持最新哦

错误过多

命名过旧

UIApplicationLaunchOptionsKey=>UIApplication.LaunchOptionsKey

childViewControllers => children

addChildViewController => addChild

calculateDiskCacheSize => calculateDiskStorageSize 切闭包返回的是一个枚举哦  size 是 Result<Success, Failure>

方法过旧

sectionInset = UIEdgeInsetsMake(0, 0, 0, 0)
修复
sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)

与系统命名重复

Alamofire 的请求request 不存在

富文本

NSAttributedStringKey ->

MJ

if ((tableView.mj_footer?.isRefreshing) != nil)

if ((self!.tableView.mj_footer?.isRefreshing) != nil)

if tableView.mj_footer?.isRefreshing != nil

self!.collectionView.mj_footer?.isRefreshing != nil

网络修改

Alamofire.request s

ImageDownloader.default.downloadImage(with: URL(string: image.url)!, options: nil) { receivedSize, totalSize in

                // 获取当前进度

                let progress = Float(receivedSize) / Float(totalSize)

                SVProgressHUD.showProgress(progress)

            } completionHandler: { result in

                switch result {

                case let .success(imageResult):

                    // 调用系统相册，保存到相册

                    PHPhotoLibrary.shared().performChanges({

                        PHAssetChangeRequest.creationRequestForAsset(from: imageResult.image)

                    }, completionHandler: { (success, error) in

                        SVProgressHUD.dismiss()

                        if success { SVProgressHUD.showSuccess(withStatus: "保存成功!") }

                    })

                    break

                default: break

                }

                

            }
