"Pre-season training is always a grind, but it's something you've got to do," said 22-year-old Dyer.
"I think the boys have been impressed with the way Curt and Pasc have picked up the mantle."
Swansea have been without a manager since the departure of Paulo Sousa last Sunday, who has since taken charge of Championship rivals Leicester City.
"The mood in the camp is still upbeat, but it's still not ideal losing your manager so close to the start of the new season,'' added Dyer, who joined permanently last summer in a £400,000 deal from Southampton after an initial loan spell.
"We are all waiting to see who the new gaffer will be. I'm sure it won't be too long before we find out.''
Chairman Huw Jenkins says he hopes to get Sousa's replacement in the Liberty Stadium hot seat by the weekend.
But until then, the squad will continue their work under Curtis and Pascoe who are likely to be in charge for Saturday's opening pre-season friendly at Port Talbot.
"Training is hard, a lot harder than last season," Dyer told the
Swansea City website
.
"But it's enjoyable, with a good mix of running and football.
"Most of the boys have come back from the break in good shape.
"In the modern game it's essential you do your own fitness work throughout the summer, otherwise when you return pre-season training will murder you."
Meanwhile Swansea City have handed Shefki Kuqi's younger brother Njazi a trial.
The 27-year-old striker had been playing for German Second Division side TuS Koblenz, where the Swans signed Shefki from in January.
