 public function setLocale();

and i get error again i try to delete

public function trans(string $id, array $parameters = [], string $domain = null, string $locale = null);

to

public function trans();

If you are using Catalina try reinstalling Valet. Another user had the same issue yesterday and a reinstall fixed it.

@apkdear You mean

@hadifox

go to youre project

for example project name WebApp

find folder vendor/symfony/translation-contracts/composer.json

and find line "symfony/translation-contracts":  change to "symfony/translation-contracts": "^1.1.6"

and now go to TranslatorInterface.php 
change to 
public function trans($id, array $parameters = [], $domain = null, $locale = null);

and go to  TranslatorTrait.php
change to
public function setLocale($locale);

and run composer update

thx

@fajar i did the same but "composer update" didn't work for me ... so I ran "composer update --ignore-platform-reqs" and it was okay...tnx
