Same error with:
cordova-ios: 6.0.0
cordova-plugin-file-transfer : 1.7.1

By removing lines 107-110 from CDVFileTransfer.m I was able to compile:

    NSString* userAgent = [self.commandDelegate userAgent];
    if (userAgent) {
        [req setValue:userAgent forHTTPHeaderField:@"User-Agent"];
    }

Thank you very much, I'll try that. You can no longer publish an app with cordova-ios v5.1.1.
This issue should be a top priority.
I have only just read that the plugin is deprecated :D.

[fabmesto]

is there any alternative to this plugin?

[alssl-ross]

I did go through the process of moving from this plugin to XHR but found that it failed for downloads of large zip files, causing me to revert back to this plugin.

I can compile now thanks to @jansc's comment above. I'm wondering if there is any effect on functionality from removing the userAgent lines. I've not been able to test for myself as yet.

Same error with:
cordova-ios: 6.0.0
cordova-plugin-file-transfer : 1.7.1

I cant not compile with @jansc Solution because Ive got: Plugins/cordova-plugin-inappbrowser/CDVWKInAppBrowser.m:27:9: 'Cordova/CDVUserAgentUtil.h' file not found if I delete Lines 107-110

That was fixed on the master branch of cordova-plugin-inappbrowser:

It's working for me.
Thank you for saving my time

Given the plugin is deprecated, is it worth creating a pull request? I'm not sure if anyone is able to merge the pull request if it was created.

I've forked this repository and made this change in if it's of use to anyone:

https://github.com/alssl-ross/cordova-plugin-file-transfer

[MrJohn2014]

Same issue here. I just comment lane 107-110 and my project could build successfully.

[hefler]

Although @alssl-ross did a fork removing the lines, I thought about combining @kolbasa 's solution tip into an own fork so that checking still happening: https://github.com/zoopit/cordova-plugin-file-transfer

[sc0ttdav3y]

Please @alssl-ross create a PR, and hopefully someone with access can merge it in.

[EinfachHans]

I switched to use this Fork

    NSString* userAgent = [self.commandDelegate userAgent];
    if (userAgent) {
        [req setValue:userAgent forHTTPHeaderField:@"User-Agent"];
    }

After deleting, my network request will not succeed. It seems that userAgent is needed

I've created a thread on the dev mailing list to discuss the matter with this plugin. It would help us PMC members to understand the reasons why you rely on the plugin (too) and especially the reasons why you can't migrate to the proposed XHR/fetch alternative.

https://lists.apache.org/thread.html/r4f85264a457ca57301cea226310f920b7f08e5657924a89899ab2b58%40%3Cdev.cordova.apache.org%3E

[HarelM]

@timbru31 I have the same issue as @alssl-ross describes.
I have a few lerge files that I need to download from my server and save to the file system - total size of the files is 500Mb. Each file is between 100Mb and 300Mb. I can't split those files into smaller files because they are sqlite database files and splitting them would be a headache.
When I download them using angular/ionic http client the file is loaded into memory before I can store it in the file system using the file-plugin.
In some cases, specifically on iOS, this causes a "white screen of death".
Somewhat related to this issue (see my comment at the end)
apache/cordova-plugin-file#364
When all I want to do is download a file and store it somewhere in the application folders there's a problem in iOS and sometimes it fails when not using this plugin.
I think the problem is related to how much memory is used by the webview, not sure though...

[timbru31]

@HarelM could you please share this insight with the dev mailing list as requested? I'm pretty sure not all active PMC members and committers are watching this issue.

[rolinger]

@msudol - why don't you contribute to the project versus criticizing it. I am certain everyone would appreciate the effort.

I made no criticism, only a request. Your comment is cringy, unwarranted, and provides even less contribution than mine. Where is your PR speaking of contributing.

[rolinger]

@msudol - too bad someone can't just develop a plugin that lets us use the same methods as cordova-file-transfer

Doesn't sound like a request....reads like a whiny complaint. Just sayin'. Moving along now...

[timbru31]

Please be civil :)

I'll remove any other off-topic comments after this one without a warning. Thanks!

[mirko77]

Quick question, on cordova-ios 6.2.0 which by default uses WKWebView, is it only a matter of commenting out those 4 lines of code? Our app uploads video files around 200/300 MB, we are refactoring to WKWebView as per Apple requirements.

NSString* userAgent = [self.commandDelegate userAgent];
    if (userAgent) {
        [req setValue:userAgent forHTTPHeaderField:@"User-Agent"];
    }

@mirko77 I'm using this fork. Works for me. https://github.com/sitewaerts/cordova-plugin-file-transfer.

I created that fork to merge the fixes from https://github.com/zoopit/cordova-plugin-file-transfer plus the current commits of https://github.com/apache/cordova-plugin-file-transfer

[Noext]

still not working on cordova 10

[mirko77]

@Noext I do not think this repository ever will, try the linked forks

hub.com/dpa99c/cordova-plugin-file-transfer

thankyou, its works with capacitor 3 and last ionic/vue 2021

[FranGhe]

Just a question (I have loose some comments) but these plugins
https://github.com/dpa99c/cordova-plugin-file-transfer
https://github.com/sitewaerts/cordova-plugin-file-transfer
work for cordova 10?

Excuse my ignorance, but if they work... why to install them the command is always the same?
cordova plugin add cordova-plugin-file-transfer

I have to do something else?

[sanderschnydrig]

To anyone facing this issue this is the only one that worked for me:

(add this to dependencies)

"cordova-plugin-file-transfer": "https://github.com/dpa99c/cordova-plugin-file-transfer/tarball/446b175154491f67bc04a657041a26bc5db92b30",

This is again not working. Only the fork worked for me.

Anyone else notice that the download example in this blog post doesn't actually save the file? You can use cordova-plugin-file to do that like the example here: https://github.com/apache/cordova-plugin-file#write-to-a-file-

Thank you very much

[danielehrhardt]

npm install https://github.com/apache/cordova-plugin-file-transfer.git

[vesper8]

To anyone confused (like I was) by the above... it seems that running

cordova plugin add cordova-plugin-file-transfer installs the latest tagged release from 2018

And running cordova plugin add https://github.com/apache/cordova-plugin-file-transfer installs the master version which includes the fix

I guess tagging a new release would be pretty great

[HarelM]

I tried to push that forward but failed, there are falling tests that prevent publishing a new version of this package to npm.
If anyone is up for it, it would be great...

[rpcarnell]

I tried jansc 's solution, but when I type ionic capacitor run ios -l --external, the file goes back to what it was. Changes are reverted. Any idea of why this happens?

[danicholls]

NPM seems to have the current version (2.0.0) now. (From 09/2023.)

I don't know if there's any reason to keep using the sitewaerts version (which was a lifesaver!) or anything.
